Newbie99 Posted August 26, 2003 Share Posted August 26, 2003 Is this a standard size turbo? Just with steel internals? Any info you could muster will be great, i at a loss....... Quote Link to comment Share on other sites More sharing options...
Alex Posted August 26, 2003 Share Posted August 26, 2003 What model of Supra are they off...cause the CT-12 is what is used on a Supra MK IV. Quote Link to comment Share on other sites More sharing options...
dandan Posted August 26, 2003 Share Posted August 26, 2003 i have CT20's on my car with steel internals. Apparently they're the standard replacement from Turbo Technics, but with steel turbine not ceramic. Maybe this is what it is, unless another Toyota has the CT20 also? Anyone confirm that CT20 is the Jap/import spec turbo and the uk have smaller CT12? Quote Link to comment Share on other sites More sharing options...

Anyone confirm that CT20 is the Jap/import spec turbo and the uk have smaller CT12? Toyota uses two variants on the CT12B turbo for the MKIV There is info on the net about the CT20 turbo. I don't understand why TT would replace a whole turbo instead of just refurb/hydridising the original Quote Link to comment Share on other sites More sharing options...
Newbie99 Posted August 26, 2003 Author Share Posted August 26, 2003 Dandan, are they bigger than the standard turbo's. E.G. Bigger housing? And im guessing they won't have 360 degree thrust bearing? Cheers. Quote Link to comment Share on other sites More sharing options...
dandan Posted August 26, 2003 Share Posted August 26, 2003 Turbo Technics said these were the standard replacement turbos for the import models. The imports do have slightly larger turbos than the uk spec (i believe), everyone says they're smaller but they just that they have lighter internals as the turbine is ceramic. Someone did post pics a while back of uk/jap turbines and jap were clearly larger. (and different colour incidentally). Mine do not have a 360 degree thrust bearing and are not rated for higher boost than the stock turbos are. Can't say about yours though sorry. Has anybody taken the turbos off a jap car and seen what's cast into housing, CT12 or CT20?? Quote Link to comment Share on other sites More sharing options...
Wez Posted August 27, 2003 Share Posted August 27, 2003 Wasn`t the CT20 used on the MR2 turbo? :flame Dev Quote Link to comment Share on other sites More sharing options...

Newbie99 Posted August 27, 2003 Author Share Posted August 27, 2003 Wez mate, there basically saying this turbo is crap, so is it worth getting it uprated and repaired or should i just buy a whole new different model? Cheers. Quote Link to comment Share on other sites More sharing options...
Wez Posted August 27, 2003 Share Posted August 27, 2003 Hiya I have just been reading through it too and it does sound like they are not very good. Doing some more research now and will let you know my findings. I have found something already where someone has replaced them with the steal turbos off of a startlet but do not know enough about it to comment. Here is some info on the turbo technics hybrids, not sure how up to date this is though :- http://web.ukonline.co.uk/soarertt/turbo_hybrid_ct12a.htm Regards Wez Quote Link to comment Share on other sites More sharing options...
dandan Posted August 27, 2003 Share Posted August 27, 2003 I was told by turbo technics that the CT20 is their normal replacement for the supra tt. and that there are loads of supras running around with these replacement turbos so perhaps it's a different spec to the "old" ct20.
